Not The Creature From The Pit this time but a story which could be said, in American vernacular, both to 'blow' and to 'suck'.

It's Underworld - a production so maligned that even most of the sets refused to participate. A CSO mother lode in which Minyans are led by Minions, the proletariat dine on the very rock they mine and gravity does precisely whatever the hell it likes.

Meanwhile, Gwyneth Paltrow gets a drastic makeover, Mr Dors takes it lying down and Leela takes a fancy to a bit-part with a Rohypnol ray. Chuck in some deaf-blind guards, hordes of bored extras and some rather louche lift music and it really does feel like we're descending to rock bottom.

So 'the quest is the quest' but will Jim and Martin see Underworld as a golden moment in Who mythology or will they end up feeling fleeced?
